What steps will reproduce the problem?
1. Start the Grader
2. You get the following warnings.
./pcs/ext/process.so: warning: already initialized constant RLIMIT_CORE
./pcs/ext/process.so: warning: already initialized constant RLIMIT_CPU
./pcs/ext/process.so: warning: already initialized constant RLIMIT_DATA
./pcs/ext/process.so: warning: already initialized constant RLIMIT_FSIZE
./pcs/ext/process.so: warning: already initialized constant RLIMIT_NOFILE
./pcs/ext/process.so: warning: already initialized constant RLIMIT_STACK
./pcs/ext/process.so: warning: already initialized constant RLIMIT_AS
./pcs/ext/process.so: warning: already initialized constant RLIMIT_MEMLOCK
./pcs/ext/process.so: warning: already initialized constant RLIMIT_NPROC
./pcs/ext/process.so: warning: already initialized constant RLIMIT_RSS
The C extension has to be fixed so that we don't get this warnings any more.
